Dear David. As an "old horse" in embedded computers, I can offer a "PRO" alternative: http://www.otto-office.fr/index.cgi?accueil=+&Referrer=60297931&Page=/catalogue/AfficheOffre.cgi?refarticle=97931&xtor=AL-602&shopbot=1 This point to the plastic Mars Staedtler Eraser. You can clean the gold contact of your camera. But one *little* swing is enough. You should see the difference after the application. This eraser does not remove the gold but the dirt on it. You can train on a SD card for instance if you are not sure about this tip. G'day! --------------------------------- Xavier F.
